Changes

==History==

According to [[Death]], before there was life, the Earth, or even God and the [[archangels]], there was [[the Darkness]]. God and His archangels defeated the Darkness and locked it away rather than destroy her to maintain [[the Cosmic Balance]]. God created the Mark as the lock and key on the Darkness' cage and if it is destroyed, the Darkness will be released. God gave the Mark to his most trusted lieutenant, [[Lucifer]], but the Mark corrupted Lucifer and made him jealous of humanity which led to his imprisonment in [[Lucifer's Cage|the Cage]]. Lucifer eventually passed the Mark to [[Cain]] as part of his deal to save Abel from Lucifer's influence.

==Episodes==

===[[9.11 First Born]]===

Dean, [[Tara]], and Crowley cast a location spell intended for [[The First Blade]], but the spell sent them to the source of the blade's power; the Mark of Cain. Knowing that [[Dean]] wants the First Blade to kill [[Abaddon]], and after seeing him kill a number of [[demons]], [[Cain]] decides that Dean is "worthy" of carrying the Mark in order to wield the blade. Cain transfers the mark to Dean, where it appears on his right forearm. Cain warns Dean that carrying the mark will come at a great cost.
